Enabling or Disabling the First Connector Check
Enabling or Disabling the First Connector
Check
The first connector check feature is used to verify that the fibers are
properly connected to the OTDR. It verifies the injection level and displays
a message when an unusually high loss occurs at the first connection,
which could indicate that no fiber is connected to the OTDR port. By
default, this feature is disabled.
To enable or disable the first connector check:
1. From the main window, tap the OTDR tab then tap the
button.
